PRESSED-METAL FASTENING snncxnr non rrrnnenrrnn nnenre'ronsf' Application filed February 2, 1923. Serial No.-516,466.

To aZZ whom it may concern: v

Be 1t known that I, Josnrir ALsrAssnn-,.a citizen of the United States, residing 1n Chicago, in the county of Cook and State of Illinois, have invented certainnew and useful Improvements in Pressed-Metal Fastening Brackets for Pipe-Damper Regulators, of which the following is a specification.

My invention relates to damper controls for air ventilating and heating .ducts and the like and has special reference to a pressed metal; bracket for association with damper regulators for such ducts. I An object of my invention is to provide an efficient, cheap and strong bracket for pipe damper controls.

Another obgect of my invention is to provide a bracket tor pipe damper regulators which is formed of wrought metal and which has a portion with which co-operates means 'for securing the damper in adjusted position by a member connected to the damper and disposed adjacent the bracket.

A further object'of the invention is to provide a pressed metal damper control bracket for pipe dampers and the like.

Generally speaking, I carry out the preterred embodiment of my invention by forming a-bracket of pressed metal into substantially U shape, inverting the same as to position on the pipe in such manner that the rod or the like attached to the'damper for moving the same may pass through the bracket.

In ventilating and air heating systems, it

is customary to interpose at suitable intervals dampers for regulating the passage of air or heat through the pipes or ducts. It is usual to vary the position of the dampers by rods or the like passing through and partially in the side of the pipe, and providing a clamp for securing the rods in adjusted position for the purpose'of proper damper regulation. It has been the practice to make the brackets of cast metal but experience has shown that these break easily necessitating frequent replacement. I have over come this objection by forming the bracket of wrought metal and shaping it in such manner that a screw clamp may be employed the side of the pipe.

I In the accompanying. drawings:

Figure 1 is a vertical sectional view oi the preferred embodiment of the invention shown as applied to a branch pipe conneo-- tion; 1

Figure '2 is an enlarged sectional view or the bracket and the cos-operating clamping parts; and V Figure 3 is an'end view oi, the bracket shown in Figure 2. 1

In the lrawings, I have shown in Fig ure 1 a branch pipe connection substantially Y shaped in section and inverted asto posi-- tion, the branches being indicated at 5-,;

and 7. 'Pivoted by means of a suitable rod .8 secured in the s des of the pipe is a damper tially rectangular in elevation and is adapt- .9. The damper is shown as a vane substan:

ed: to be swung about the pivot 8 for. varying the openings through the branch. The rod 10" is fastened by means of a suitable bracket 11 to the damper or vane 9 and disposed. to pass through an opening 12 in Attached to the out.- side of the pipe is the bracket of my invention. The bracket is formed in the present in stance of sheet metal pressed into substan tially U shape and inverted as to position. T hat portion of the bracket which is adapted to be secured to the pipe has laterally extended ears 13 which are apertured for the reception of screws, bolts or otherffastening means 14 which pass through regisa tering apertures. in the pipe. is also provided with an enlarged centrally disposed opening 15 through which the rod .10 passes. The'other 'leg 16 of the bracket has a similarly disposed and registering This portion.

opening 17 therein through which the. rod

Against the under side of the central portion of the bracketis employed a nut 20, preferably a square nut, disposed so that one of its edges will engage the shoulder. 19 and receive the threaded portion of the screw 18. The central portion of thef throu gh both side end thereof will bear against the rod. The i clamping effect is caused by the screw 18 bearing against therod between the apertures '15 and 17 of the side members of the bracket, and the screw is maintained in posi- 1 tion by reason of its cooperation with the an which is prevented. lrointurning by engagement oftheinut with the shoulder-19 slant ed in the bracket. After moving the vane the screw may be loosened and the rod 7 moved inwardly or outwardly as desired and secured in adjusted positioniby tightena the screw. 18 thereagainst.
